    Idling issues I'd suspect vacuum hoses to be split or not attached properly. The normal suspects are the ones under the manifold.

    That code is to do with the cooling system but you've changed the temp sensor, have you changed the stat?

    17704/P1296/004758 - Error in Mapped Cooling System
    Possible Symptoms

    Cold start issues

    Possible Causes

    Coolant Temperature Sensor (G62) faulty
    Coolant Thermostat faulty

    Possible Solutions

    Check Coolant Temperature Sensor (G62)
    Check Coolant Thermostat

    Special Notes

    Check the stored Freeze Frame data with this fault code. Freeze Frame information will be found in the fault code description (if the module supports it) or in Generic OBD-II if the vehicle complies with those regulations.
    Freeze Frame data stored at -40 °C is generally an indication of a faulty ECT or wiring.
    Freeze Frame data stored at +140 °C is generally an indication of a faulty ECT or wiring.
    Freeze Frame data stored with in the 60-80 °C range is an indication that the vehicle was close to, but not within, the cooling systems normal operation range. The Thermostat itself or Cooling system components may be at fault.

    Get the stat changed...
